~2- | ‘ effects. Radiation there is too.slight for medical studies to be of interest since no radiationeffects would likely be detectable. The urine collection and measurements of the body for radioactivity are not medical procedures and are done by technicians. These measurements are important since they form the basis for reassurance of the people living onBikini regarding their radiological safety. Though we are not doing medical examinations “if our doctors are at Bikini, as in the past, we will always be glad to see, treat and prescribe for any people that are sick - but only at the request of the individual or the health aide. Unless requested by the people it is not even necessary for our doctors to go to Bikini. In’ 1969,personnel monitoring procedures were begun on a group of 30 worlamen at a work camp on Eneu Island. \ By 1972 about 3 Bikini families 7 en had moved back (about 50) and also about 25-30 workers and agriculturists. " Radiological monitoring at Bikini has been carried out annually since 1969. The size of the population has not changed much ‘since 1973. In order to assess the radiological hazard the following personnel monitoring procedures have been carried out: 1. Radiochemical analyses on urine samples: pooled samples). (individual 24 hour and These analyses require complicated chemical procedures and ate done for us by the ERDA Health and Safety Laboratory in New York ' City. Such radiochemical analyses have also been carried out on water and local food products. 2. Direct measurement of radiation in the people by gamma spectro- _ graphic analysis: To do this tons of radiation-free lead bricks were shipped to the Marshalls and a shielded counting facility set up in one of our airconditioned trailers and transported to Bikini on our vessel (LCU-Liktanur). eg TP STERE FEPETE TI,FEE OTe ARE me re oe gh as any ae toe ot > oa@,, a ON pelea stro -. fo . :et 9 te Wye age > 3 rege.
